To allie/wm .it may concern:

Be it known that I, EDWARD T. CURRAN, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Radiators, and declare the following to be a full, clear, and eXact description of the same, such as will enable others skilled in the art to `which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to radiators for automobiles and analogous vehicles in which water cooling of the engine is a necessity, and consists in the arrangements and combination hereinafter described and claimed.

In the drawings:

Figure 1 is a sectional view on the line Fig. 2.

Fig. 2 is a front view of the radiator with the covering shell.

Fig. 3 is a sectional view on the line g/-g/ Fig. 1.

' Fig. 4 is a cross-section on the line @/-y Fig. 2.

Similar letters refer to similar parts.

In the drawings A represents the shell or covering of the radiator in the usual conventional form. The radiator is divided into two halves with a filling hole a or a on each, which halves are placed together to make the complete radiator but which may be used singly as described in my revious application Serial No. 241,326. A frontal hollow shell B is combined with the interior hollow shell C by means of conical passages D, D. The interior shell of the hollow passage ways D D aiiords conical air passages E E in the shape of a rustum of a cone. Behind the radiator section C' is a thin water receptacle F which is not perforated but is smaller than the receptacle B C, allowing air to pass around it. All these terminate in a head G which also may inclose water and which unites all sections B C F. The water spaces in this compound radiator are connected respectively at top and bottom with the water jacket of an engine H by the usual conventional pipes J J. Between the radiator compartments B and C and surrounding the conical water passages D'D is an open space ai, which communicates at K with the open air'and is allowed to pass over the top of the radiator at L. A deector M on the motion of the 'car scoops the air and forces it upward and around the conical water spaces D D and out over the top at L under the hood of the engine. The rear section F not being periorated the air is constrained, after passing through the conical openings E, to strike against the section F and it will be deflected at right angles and then part passes through the central aperture between the two halves of the section, as is shown in my former application, and the remainder passes around the edges of the section and thence around the engine under the hood and outward. By this means I am enabled to make a more eliective radiator than the one previously described in my former application. a, a are lling holes and P is the conventional cover` or hood over the engine and radiator constructed and applied in the usual manner. It will be noted that the air passing through the conical passages E E is not mingled with the air which passes in at K yand is deflected upwardly around the conical water jackets D D. In Fig. 3 I have shown a cross sec-tion of the conical water passages and the front of the reservoir C'. I also have shown that the radiator is double, dia vided by a division line at Q Q. Any means may be used to rigidly hold these two sections in position and in ordinary use the water spaces may be united so that water circulates throughout both of them. Although I have shown no provision in the radiator for uniting the water spaces, they are united as such by means of the water jacket of the engine H. It follows therefore that if one part be dispensed with or is not in use by closing oli the passages to that side from the engine the other part could be used with the whole water space in the engine communicating with it and cooled by it. Of course as ar as the communicating pipes J J are concerned they may be rights and lefts.

m Fig. 1 is a small pipe for the escape of steam or air. n indicates a constriction at the lower end of the receptacle F through which it communicates with the return pipe QI. I

The operation of this device is readily understood by the foregoing description.

What I claim is:

l. In a radiator, the combination of two water receptacles connected by forwardly' directed conical air pipes, each having a circumferential water jacket forming a communication between said receptacles, in coinbination with a third receptacle located s oV three receptacles, two adjacent receptacles having an air space therebetween, air conducting pipes surrounded by water passagesV v10 connectingl said adjacent receptacles and passing through said air space, the third receptacle being` located so as to oppose one of its surfaces in the lines of travel of the jets of air proceeding from said air pipes, and means whereby air is permitted to pass upward through said space, substantially7 as described. Y In testimony whereof, Ik sign this specification( `ED'WARD T. `GURRAN.
